reissue specification;

The present invention relates to new and useful improvements in thread carriers and more particularly to thread carriers for full fashioned hosiery knitting machines and the like, wherein the thread is payed out through a replaceable thread guiding tube which is removably mounted on the thread carrier.

An important object of the invention is to provide a thread carrier designed to prevent costly damage to sinkers and needles as Well as to other parts of the machine and which is an objectionable feature to the present type of high speed hosiery machine. To overcome this objection I provide a turret in which the thread carrying tube is mounted whereby the tube may swing toward either side out of line with the sinkers and needles and thus prevent damage to these parts.

A further object of the invention is to provide a removable mounting for the thread carrying tube to facilitate replacement thereof Without removing the carrier from the machine.

A still further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the thread carrier with the tube supporting turret mounted in position therein,

Figure 2 is an enlarged front elevational view,

Figure 3 is a transverse sectional view taken substantially on the line 33 of Figure 2,

Figure 4 is an enlarged fragmentary front elevational view with the turret and thread carrying tube removed,

Figure 5 is a plan view of the turret, and

Figure 6 is a transverse sectional view taken substantially on the line 6--6 of Figure 4.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates the thread carrier which comprises substantially a metal strap having a thread guiding groove 6 of gradually increasing depth and width extending longitudinally thereof toward its free end. The carrier 5 is provided with a pair of spaced parallel longitudinally exmatter printed in italics indicates the additions made by reissue.

2 tending slots 1 extending inwardly from its free end to provide a pair of fingers 8 at the side edges of the carrier at each side of a central finger 9 which carries the groove 6.

The outer ends of the fingers 8 are curved oppositely to form arcuate jaws III, the inner edges of the upper and lower surfaces of which are rabbeted as shown at II to form an inwardly projecting arcuate flange I2 on the opposed edges of the jaws I0 and positioned midway between the upper and lower surfaces of the jaws as shown more clearly in Figure 3 of the drawings.

The end of thecentral finger 9 is formed with an outwardly extending tongue I3 of semi-cylindrical form to provide a rounded under surface as shown at I4.

A turret in the form of a disc I5 is formed in its peripheral edge with a groove I6 to receive the flanges I2 of the jaws ID by sliding the turret inwardly between the jaws to rotatably lock the turret therebetween by a snapping action.

The upper surface of the turret I5, at its inwardly disposed edge, is cut away or rabbeted as shown at I! to expose the inner edges of the flanges I2 and a groove I8 is formed in the rabbeted portion IT to receive the tongue I3 in a snapping action.

A bore I9 extends transversely of the turret I5 in alignment with the groove I8 and in which a thread carrying tube 20 is removably positioned,

the outer end of the tube projecting outwardly beyond the outer edge of the turret.

In the operation of the device, the turret I5 with the thread carrying tube, 20 therein is snapped into position between the jaws II] by, sliding the turret inwardly on the flanges I2 and with the tube held aligned with groove 6 by tongue I3 snapped in groove I8 of the turret.

The turret is free to swing toward either side should the outer end of tube 29 strike the sinkers or needles of the machine (not shown) to thus prevent damage to the machine.

The outer end of carrier 5 is curved downwardly at a desired angle in accordance with the type of knitting machine on which the same is used.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprebended the. p ritoi. the vention s. h rein.
